Editing Michigan left (section)

==Variations==
===Narrow median===
When the median of a road is too narrow to allow for a standard Michigan left maneuver, a variation can be used that widens the pavement in the opposite direction of travel. This widened pavement is known as a "bulb out"<ref name=thruturn/> or a "loon" (from the pavement's aerial resemblance to the [[loon|aquatic bird]]).<ref name= FHWA2/> Such a design is sometimes referred to as a ''Michigan loon''; in [[Utah]], as a ''thrU turn'', where one passes ''through'' the intersection before a ''U-turn''.<ref name=thruturn/>

===Grade separation===
In [[Guadalajara, Mexico]], there is a grade-separated variation of this setup at the intersection of Mariano Otero Avenue and Manuel Gómez Morín Beltway ({{coord|20.630666|-103.434981|dim:100|display=inline}}).<ref>{{google maps |url = https://maps.google.com/?ie=UTF8&ll=20.630666,-103.434981&spn=0.003695,0.006899&t=k&z=17 |title = Mariano Otero Avenue and Manuel Gómez Morín Beltway, Guadalajara |access-date = December 20, 2010 |link = no }}</ref> [[Traffic flow]]ing through Mariano Otero Avenue is routed onto an overpass above the beltway, with two access roads allowing right turns in all four possible directions; the U-turns, meanwhile, are built underneath the beltway and allow the left turn movements from Mariano Otero Avenue to the beltway.

===Superstreet===
{{main article|Superstreet}}
A variation of the Michigan left that prohibits through traffic on minor roads from crossing the major road or highway, is most commonly called a superstreet or a "restricted crossing U{{nbh}}turn" (RCUT).<ref name=FHWA-RCUT>{{cite web |author = Federal Highway Administration |author-link = Federal Highway Administration |title = Restricted Crossing U-Turn Intersection Informational Guide |url = https://safety.fhwa.dot.gov/intersection/alter_design/pdf/fhwasa14070_rcut_infoguide.pdf |archive-url = https://web.archive.org/web/20150424161246/http://safety.fhwa.dot.gov/intersection/alter_design/pdf/fhwasa14070_rcut_infoguide.pdf |url-status = dead |archive-date = April 24, 2015 |page = 10 |date = August 2014 }}</ref> In contrast to the standard Michigan left, left turns from the major road or highway to minor roads are usually allowed, although there is a variation that prohibits such turns.
